Claims

[Scope of utility model registration request]

(1) A frame that is formed in a U-shape and is configured such that the back member and both side members forming the above-mentioned U-shape can be attached to the support portion, respectively, and the both side members that are parallel to the back member of the frame. two shafts at the rear and front supported by the rear and front shafts; rear and front rollers in hollows rotatably supported via bearings respectively on the rear and front shafts; and front and rear rollers of the cable. One end of the front shaft is rotatably supported around the one end in a plane that includes the axes of the front and rear shafts, and the other end is supported by the frame. A cable extension support device characterized in that it is configured to allow the front roller to be held in a predetermined position and rotated by moving in and out of a puller provided in the side member on that side. .

(2) The cable extension support device according to claim 1, wherein the bearings for supporting the front and rear rollers on the front and rear shafts are either ball bearings or roller bearings.

(3) A flange in which a device for preventing the cable from digging in from the low length is provided at both ends of the front and rear rollers so as to be close to each other;
and a utility model according to claim 1 or 2, which comprises at least a flange of anti-biting fittings attached to both frames and formed along the circumferences of both ends of the front and rear rollers. Cable extension support device.

(4) The pin for holding the front roller in a predetermined position and rotating it is a U-shaped pin that is provided through the frame in a direction perpendicular to the front and rear axes, and one side is longer than the other. A spring is installed between the long end and the frame to constantly move the pin toward the front end, and when the pin is pulled toward the rear end, the front shaft end comes off the short side of the pin. A cable extension support device according to any one of claims 1 to 3 of the utility model registration claims, which is configured as follows.
